Adjustable pipe sleeve with floor and ceiling plate



ADJUSTABLE PIPE SLEEVELWITH FLOOR AND CEILING PLATE Filed June 11, 1957 INVENTOR WTTOR EY Patented Nov. 9, 1937 UNITED STATES PATENT OFFICE ADJUSTABLE PIPE SLEEVE wrrn FLOO AND CEILING PLATE My invention relates to a pipe sleeve for use in concrete or other types of ceilings, walls, or

floors. v

Heretofore in the use of sleeves for pipes to pass through when. buildings are being constructed,

. it has been customary to take a short piece of pipe having the desired internal diameter and to place a cap over one end. Then a long bolt is placed through the cap,- and the bolt is screwed into the wood form. With the above arrange ment, the head of the bolt protrudes above the floor and isin the-way, particularly when the floor is screeded. The pipe forming the liner also has an opportunity to shift a distance which is approximately the radius of the pipe, since one end of the pipe is not securely held in position. I

It is an object of my invention to securely and accurately hold the adjustable pipe sleeve in positionon the wooden forms about which concrete is poured.

Another object of my invention is to construct an adjustable pipe sleeve which will screw in or out of concrete that has hardened. about the pipe sleeve. 1 25 Another object of my invention istoprovide a water-proofadjustable pipe sleeve or tubewhich is adapted to pass through floors, ceilings, boards or partitions of various thicknesses either in buildings, boats, or other related places. 30 It is anotherobject of my invention to provide a pipe sleeve whichis adjustable to any thickness of floor, wall, or partition.

Another object of my invention is to provide a pipe sleevewhich eliminates all bolts and screws.

Another object of my invention is to provide a sleeve which will not interfere with the screeding of floors.

Another object of my invention is to provide a pipe sleeve through any materialin a vertical 40 position which extends just above the floor and,

therefore, prevents water from seeping around thepipe whenthe floors are scrubbed.

Another object of my invention is. to provide a pipe sleeve which can be used in old as well as 5 in new buildings.

Another object of my invention is to provide a pipe sleeve which has a flange formed therewith so that the flange can be painted to match the pipe, thereby eliminating extra floor and ceiling 50 pipe plates.

Another object of my'invention is to provide a pipe sleeve wherein the flanges may be easily positioned the correct distance from each other andalso'aproper distance from any'wall orpar 55 tition.

Another object of my inventionisto provide, a pipe sleeve which cannot be driven through the wall, floor, 0r partition after it is: in place.

'It is the present-custom to attach floor and ceiling plates directly to the pipes by set screws 5 or springs which are displaced by the movement of the pipes; With my invention the floor and ceiling plates remain in a permanent fixed position and are not'displaced bythe expansiom-contraction, ormovement-of'the-pipes; 7 I

Another object of my invention is the provision to attach other additional commercial size floor and ceiling plates directly to the flanges of the sleeves.

Other objects of my invention are to providean 15- improved device of the character described that is easily and economically produced, that is sturdy in construction, .andis .eflicient for the use to which it is placed. I l

With the above and related objects in view, my invention consists in the following details of construction and. combination of partsthat will be more apparent when the drawing is read in conjunction with the following specification.

In Fig. 1 is a fragmentary sectional view of a buildingshowing my improved pipe sleeves in the floors and in a vertical walls Fig. 2 is a plan view of one part of my new pipe sleeve. 7

Fig 9 is a side elevational view of my improved adjustable sleeve with the lower flange fastened to a wood form preparatory to the filling in of the concrete about the form. The paper liner is omitted.

Referring now in detail to my invention, I show in- Fig. 1 a fragmentary portion of a building, erally designated as A, which has a vertical side wall In and a vertical inner wall l2 and floors designated as l4, l5 and IS. The floors have therein adjustable pipe sleeves, generally desig- The pipe sleeve B is comprised of a metal flange l8 which has a large centralopenihgZll therein,

and its end 2| is downturned to retain. a. small gasket 22 which surrounds theinner-portion of r the flange l8 to make the sleeve waterproof; plurality of suitable spaced holes-23,14, 25, 26,

21 and 28 are in the main annularflange portion to receive nails whereby the device is held in place or to receive a tool whereby the sleevesmay be turned and to receive an additional separate corn merciafstahdard size flooror ceiling plate as desired f I 4 a V A female threadedsleeve 30 passes through the opening 20 in the flangel8- and also isinserted within'one end of an oil or parafllne-coated cylin= drical papertube 32. The out'erend of the sleeve 30 and the flange are united by a driving flt and flattened pipe 'onsaid flange 30- so they turn as one Piece. 7 v v Interfltting withthe female sleeve 30 is a male sleeve 34 which passes through aflange 36 and into the other end of the paper tube 32. The

- flange 36'and the outer'end of the sleeve 34 to contract the pipe sleeve.

are united by a driving fit and flattened type so that'th'ey turn as one piece.

The physical construction of the tube s1eeve'32 is shown in Fig. 6, that isthe'paper tube 32 en tively smooth so that the threaded sleeve may berotated'to open or to closed'positionf The operation of turning the pipe sleeve is performed by inserting a tool in any of, the flange openings and rotating the sleeve.

By the use of the paper sleeve, it should be apparent that during the pouring of concrete into the form of the building for either a floor, wall orceiling, no concreteor liquidwill pass 'between the' interlocking threaded portions in order to solidify there and to preventthe moving or unscrewing of one, of' the parts with respect to the other. This is'of considerable importance in pipe sleeves which. are inserted in newly poured floors, walls, or ceilings.

In certain places such as in concrete, the tube 32 may be oil or parafine coated, but when the sleeve is used in a wood floor or ceiling, the tube should be of asbestos or of non-combustible matter.

It has been customary in constructing buildings to form.openings in the walls'or ceiling to run steam or other pipes through the openings, and then to cover theoutside of this'sp'ace with a floor or ceiling plate, separable cap or ring both. at the entrance or exit to the opening.

With'my invention it is apparent that at-the outset I can slip the proper pipe through the sleeve opening without the necessity of using any packing subsequently and that the flanges l8 and 36 neatly cover the space surrounding the pipe opening. 7

While the foregoing description has been generally applied to the use of my invention for concrete structures, it is also within the scope of my invention to employ the device in wooden or other structures where an adjustable pipe sleeve is desired.

A modification of myv invention is shown in Fig. 8 where a flange 2IA is integrally pressed with the threaded sleeve 30A. Both the male sleeve and the female sleeve are constructed of one piece of metal.

My invention is assembled as follows:

The wooden forms such as 31, Fig. 9, on the wall or ceiling are nailed or supported in place. Then either the male or female part of the sleeve, such asthe sleeve 34,"is located in position on the wooden form-nails or'other fasteners 33 are driven through each of the holes 23 to '28. With one portion'of the sleeve in place, the sleeve 32 is-placed over the fastened sleeve portion, and then the upper sleeve portion 30 is inserted in the upper end "of the tube and turned so the threads on the male and female sleeves interlock. The length of the sleeve is adjustable to the thickness of the'floor.

After the concrete is poured into position and is hardened or in a semi-hardened condition, each ment' of the pipes, and that the sleeves cannot be driven through'any substance in which they may be embedded or held. 1 Q

Although my invention has been described in considerable detail, such description is intended as illustrative rather than limiting since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.

I claim as my invention: 1. .A pipe sleeveadapted to be inserted'in the space deflning the floor prior to the pouring of concrete which comprises a sleeve having its curved bounding surface threaded, a complementary interfltting sleeve with threads upon its curved bounding surface whereby the sleeves may be screwed together in order to extend or contract the length of the sleeve,'a paper tube surrounding the curved bounding surface of the interfitting sleeve parts. 7
